The display of Chinese.The character library of Qt support these four formats of TTF, BDF, PFA/PFB and QPF.If straight in embedded board
It connects using PFA/PFB, then application program can just calculate dot matrix when display, final the effect is unsatisfactory, word occurs
Body situation not of uniform size.And this font occupies very more FLASH and memory, and loading velocity is also relatively slow；BDF font
There is identical problem；Although the load of QPF font speed is fast, font pantograph is not supported；TTF font not only supports font to contract
It puts, and loading velocity is very fast, therefore uses TTF format font in reader.
As shown in Figure 3 and Figure 4, voice synthetic module 2-5 is by text analyzing, rhythm processing and speech synthesis three parts group
At completing the conversion of Text To Speech.The text of input is mainly decomposed into phoneme by word or word by the work of this process, and
And the symbol of specially treated is wanted to analyze number, monetary unit, word deforming and the punctuate etc. in text, and by sound
Element is generated then digital audio plays back or save as audio files with loudspeaker after and is played with multimedia software.Wherein,
The main task of text analyzing has: 1, pre-processing to the text of input, so that text normalization.Specific way is such as removed
Punctuation mark is converted into some special labels by some extra spaces or newline, such as the dead time is identical
, tone changes consistent punctuation mark and is uniformly converted to certain special marking.It, can be significantly local after standardization processing
Just it segments.2, it segments.After the text standardized, text is cut into several word and word.Participle is the important group of text analyzing
At part, simplest segmenting method is exactly to look up the dictionary.Participle is realized using method of looking up the dictionary, and is in fact exactly a sentence from a left side
As soon as scanning time to the right, the word that encountering has in dictionary is identified, encounters compound word and longest word is just looked for match, encounter and do not recognize
Word string be just divided into monosyllabic word, then simple participle just completes.It 3, is phonetic symbol table by the text conversion after decomposition
Show form and adds command character.The word and word obtain to participle searches its corresponding phonetic symbol and then is stitched together, and completes by words
To the conversion process of phonetic symbol.
The input that the result of text analyzing is handled as the rhythm.Rhythm processing is mainly handled tone, rhythm etc..
Such as when there is continuous two third sound, falling tone just is carried out to it, so that synthesis voice is correctly expressed the meaning of one's words, sounds more certainly
So.
Input in the last speech synthesis stage, by the output of rhythm processing module as voice synthetic module.Voice
Synthesis module searches corresponding example for each phonetic symbol in sound bank, then by the corresponding all notes of text sentence
The example of phonemic notation is stitched together, in splicing according to command character it is semantic to the duration of a sound of voice example, prosodic features and
Dead time etc. is adjusted, and finally exports the complete phonetic data flow of a sentence.
Speech synthesis is realized using above method, and the calculation amount needed is small, aggregate velocity is fast, and synthesizes speech naturalness
It is higher, it is clear that be relatively more suitable for the application in terms of the weaker embedded system of chip performance.Realize speech synthesis, it is also necessary to complete
At several preparations: 1, the mapping table of creation Chinese characters in common use Unicode code to phonetic symbol；2, common phrase Unicode code is created
To the mapping table of phonetic symbol；3, Chinese sounds library is created.Voice bank has recorded the pronunciation of whole phonetic symbols in mandarin and Guangdong language, by word
With the wav formatted file composition that word is unit.
User client and server are communicated using Unix domain agreement.With client and server on the same host
TCP compare, the advantage of Unix domain byte stream socket is embodied in the growth of performance.
The electronic reader module realizes user interface using QML, realizes the page in QML insertion JavaScript code
Logic, speech synthesis are realized by the speech interface that Microsoft Speech SDK 5.1 is provided.Microsoft Speech
SDK provides a set of application programming interface SAPI about speech processes, and SAPI provides the basic letter for realizing TTS program
Number provides a high level interface for one between application program and speech engine.SAPI realizes all required to each
